Combination cardboard shipping and display carton

ABSTRACT

A carton, fabricated of corrugated cardboard or other suitable material, which at its shipping destination, i.e. a retail store, is adapted to be separated along a tear strip into two parts, to thereby enhance the display and sale of the products within the carton. To minimize any tendency of the carton to burst during shipping service because of said tear strip, the side flaps are oversized and are folded into the clearance between rows of the shipped products to minimize any shifting movement in these products, and thus to correspondingly minimize the strain imposed on the external carton walls.

ABSTRACT 4 Claims, 7 Drawing Figures PATENTED HAY 2 0 I975 SHEET 10F 2 PATENTED HAY 2 01975 SHEET 2 OF 2 COMBINATION CARDBOARD SHIPPING AND DISPLAY CARTON The present invention relates generally to cardboard cartons, and more particularly to improvements for a cardboard carton which facilitate converting it into a product display, but without adversely affecting its main function of protecting products during shipment.

It is a common practice in retail stores to cut apart cartons preparatory to using the resulting separated parts as a display for the contents. The patent literature, as exemplified by U. S. Pat. Nos. 776,042, 2,487,168 and 3,669,251, discloses an effort to achieve the same objective by using a tear strip in the carton which, when removed, divides the carton in two. The perforations in the cardboard carton walls which permit removal of the tear strip, however, also render these walls vulnerable to rupture. It is undoubtedly because of this that shipping cartons with tear strips are not in popular use.

Broadly, it is an object of the present invention to provide an improved tear strip-type carton overcoming the foregoing and other shortcomings of the prior art. Specifically, it is an object to obviate any tendency of the external carton walls to rupture, despite the tear strip therein, by effectively immobilizing the shipped products against any shifting movements as would subject the carton walls to undue stress and strain.

A combination shipping and display carton demonstrating objects and advantages of the present invention includes panels, fabricated of cardboard, which cooperate to bound a shipping compartment, and which further includes an encircling tear strip for separating the carton into two display halves. Supplementing the external construction of the carton are internally positioned flaps whichextend between the rows of the products to maintain the position of the products, i.e. prevent any shifting therein, during shipping use of the carton. As a consequence, an optimum minimum degree of force is exerted outwardly against the carton walls, and the carton also has been found in practice to be better adapted to withstand shearing and other forces which might otherwise cause premature rupture and disengagement of the tear strip.

The above brief description, as well as further objects, features and advantages of the present invention, will be more fully appreciated by reference to the following detailed description of a presently preferred, but nonetheless illustrative embodiment in accordance with the present invention, when taken in conjunction with the accompanying drawings, wherein:

FIG. 1 is a plan view of a cardboard blank which forms into the carton of the present invention;

FIG. 2 is a perspective view illustrating the folding procedure for forming said carton;

FIG. 3 is a perspective view illustrating the carton hereof in its folded condition preparatory to use in shipping products;

FIG. 4 is a side elevational view, in section taken on line 4-4, illustrating structural features of the carton, and wherein positions of one of the carton flaps is illustrated in full line and phantom line perspective;

FIG. 5 is a perspective view illustrating the manner in which a tear strip is removed to separate the carton into halves preparatory to using each half for display purposes;

FIG. 6 is a view similar to FIG. 5, but illustrating the almost complete removal of the tear strip, and also a preferred position for the carton to facilitate its separation; and

FIG. 7 is a perspective viewillustrating the display that is provided by the separated portions of the carton.

Reference is now made to the drawings, and initially to FIGS. 5-7 which best illustrate the benefits obtained by using the carton hereof. Said carton, generally designated 10, includes a tear strip 12 which is readily removed along spaced apart perforations, at 14 and 16 (note FIG. 5), with the result that upon its complete removal, carton 10, as illustrated in FIG. 6, divides into two parts 18 and 20. By laying carton 10 on its side, and after removal of the strip 12, it is thus possible to separate the carton parts 18 and 20, and more particularly the products, individually and collectively designated 22, which are contained within the carton 10. As illustrated in FIG. 7, the carton separation, as just generally described, contributes to the use of the resulting two carton protions or parts 18 and 20 for display purposes. To enhance the display provided by the carton parts 18 and 20, the lines of perforations 14 and 16 which, as noted above enable removal of the tear strip 12, are advantageously angularly oriented so as to provide correspondingly angularly oriented edges to the carton parts. At the low side of the carton this, in an obvious manner, provides the customer with visibility of the brand name of the product 22 and also makes it easier for the customer to remove the product from the carton.

Although it is well known in the patent literature to provide cartons with tear strips so as to facilitate their division, these prior art cartons do not provide dependable shipping service because the weakness in their construction, represented by the tear strip, made the same vulnerable to rupture during shipping. In contrast, the strength of carton 10 hereof is sufficient to withstand rupture and to meet commercial standards, despite the existence of the tear strip 12.

As illustrated in FIGS. 1-4, tear strip 12 is embodied in a pair of side panels 24, 26 and a pair of end panels 28, 30, all of which cooperate in a conventional manner to form a body for the carton 10 which bounds an internal shipping compartment 32 (see in particular FIG. 3). That is, in forming the blank of FIG. 1 into a carton shape as illustrated in FIG. 3, the body panels are folded along three fold lines 34, 36 and 38, and flap 40 is then folded, as at 42, and adhesively secured along edge 44 of end panel 30. In this partially completed condition of the carton 10, the panels bound opposing rectangular openings 46 and 48 into the shipping compartment 32.

Thus far what has been described is conventional. Also conventional are extensions on opposite sides of the end panels 28 and 30 which serve as closure flaps, individually and collectively designated 50, and which are appropriately sized and adapted, when folded into the openings 46 and 48, to function as a closure for said openings. This function of the flaps 50 is illustrated in FIG. 4.

Prior to closing the carton with the flaps 50, however, use is made of novel side flaps to supplement, as noted earlier, the strength and ability of the carton 10 to withstand rupturing forces. In other words, it is the'use of the side flaps in a manner which will now be described,

which constitutes the novelty of the present invention and which makes it possible to use a tear strip 12 in the construction of the carton without detracting from the shipping performance of the carton. These side flaps, designated 52 and 54, are formed as extensions on opposite sides of the side panels 24 and 26. Since the side flaps are identically constructed, the description of one such flap suffices for all and, for the sake of brevity, a functional description once given will not be repeated if it does not contribute to an understanding of the invention.

Taking flap 52, by way of example, which extends from the upper portion of side panel 24, and referring specically to FIGS. 3 and 4, it will be noted that this flap is constructed so as to provide a productpositioning function for the products 22 in shipping condition within the shipping compartment 32 of carton 10. More specifically, said product-positioning flap 52 has a fold line 55 spaced from and parallel to its connected edge 56 which delineates a first portion 58. Portion 58 is well adapted by its location and size to fold over the top of the row of products 22 located adjacent the side panel 24. The remaining portion 60 of flap 52 is then folded into an operative position projected internally within the shipping compartment 32 wherein it occupies a position along the side of the row of products 22, just referred to as being adjacent the panel 24. It is to be noted, in fact, that the edge 62 of the flap portion 60 is conveniently projected within the clearance 64 existing between adjacent rows of the products 22. As a consequence of this, and also as a result of placement of a row of products in the medial section of the shipping compartment 32 after providing flap portions 60 with their operative position, the vertically oriented flap portions 60 of the flaps 52 of both openings 46 and 48 cooperate to function in much the same manner as vertical dividers within the carton shipping compartment 32. As a result of these vertically oriented flap portions 60 between the rows of products 22, said rows are prevented from shifting within the compartment 32 during shipping use of the carton 10. This, in practice,

has been found to minimize and, for all practical purposes, obviate any tendency in the carton 10 to rupture when subjected to handling forces and compressive forces which are the normal consequences of shipping use or service of the carton 10.

Returning again to FIG. 7, it will be noted that to enhance the display provided by the separated carton parts 18 and 20, that the lines of perforations l4 and 16 are advantageously embodied in the body side panels 24 and 26 at an angular orientation, as illustrated. As already noted, this aids in exposing the brand name of the products 22, which may be located in areas 66 on the product. Since the edges 14, 16 are angularly oriented, it is preferable also that the same or a substantially similar angular orientation exist in the free edge 62 of each of the flap portions 60. As illustrated in FIG. 7, the orientation of edge 62 is actually somewhat steeper than that of the edges 14 and 16 in order to provide the triangular section 66 which extends more than one-half the height of the shipping compartment 32 and thus into the clearance 64 to prevent any relative shifting between the products 22 which might otherwise occur between the upper and lower layers of the products, as at 68 (see FIG. 4). When carton 10 is separated into its two display parts 24 and 26, the holding sections 66 are no longer necessary, and to enhance the display, they are therefore preferably removed,

5 v which is the reason for the line of perforations 70.

that there has been described herein a carton l0 fabricated of cardboard which readily permits not only scoring to provide fold lines, but also the incorporation of lines of perforations to define a tear strip 12. While the use of perforations ordinarily detracts from the strength of the cardboard, and thus would render the carton 10 vulnerable to rupture along the tear strip 12, this is overcome in a novel fashion wherein the carton makes use of side product-positioning flaps 52 and 54 to retain, as the name implies, the position of the products 22 within the shipping compartment during shipping service of the carton. Since the products 22 are prevented from shifting relative to each other, there are no shearing forces imposed upon the carton 10 which could produce rupturing in the lines of perforations l4, 16.

A latitude of modification, change and substitution is intended in the foregoing disclosure and in some in stances some features of the invention will be employed without a corresponding use of other features. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the spirit and scope of the invention herein.
